PlLECASIOPHORA, 



[PL iii., fig. 10.] 

 Phcecasiophora variabilis, sp. n. 



Antenncz simple ; greyish fuscous. Palpi short and compact 

 the apical joint small, greyish fuscous above, paler beneath. Head 

 greyish fuscous, clothed with short rough scales. Thorax the same 

 colour as the head. Fore wings greyish fuscous, paler along the 

 first half of the dorsal margin, and sometimes with a pale diffused 

 patch on the costal margin before the middle, in which are two or 

 three small dark costal spots; beyond this is a short brownish 

 fuscous oblique costal streak, followed by others of the same 

 colour close to the apex; the most noticeable marking on the wing 

 is a large dark brown patch above the anal angle, paler about the 

 angle itself, but reaching nearly half-way along the dorsal margin, 

 and approaching the costa before the apex at its upper end, where 

 it is deflexed to a point above the middle of the apical margin ; 

 this patch is edged with a slender ill-defined greyish white line 

 throughout its inner and upper margin, which meets a short 

 slender greyish white streak coming from the costa immediately 

 before the apex ; in the darker portion of the wing is a somewhat 

 distinctly darker shade along the first half of the fold ; cilia 

 greyish white at and below the apex and above the anal angle, but 

 dark brown along the middle of the apical margin. Under side 

 unicolorous pale brownish fuscous, the cilia dirty whitish about the 

 apex and anal angle. Hind wings brownish fuscous; cilia greyish 

 white, with an obscure dark line along their base. Abdomen 

 brownish fuscous. Exp. al. 21 mm.

The species appears to be variable ; the general pat- 

 tern of coloration is probably maintained, but the colours 

 vary from dark greyish fuscous to reddish brown, or 

 chestnut-brown, and perhaps even to other tints in an 

 extended series. 



The African form of this genus differs from the North 

 American type, as described by Grote, in having strong 

 tufts of scales on the hind legs in both sexes (not in the 

 male only). It is interesting to find that not only does 

 the allied genus Eccopsis of Zeller (equal Clemens' North 

 American Exartema), but that this North American 

 genus, described by Grote (Bull. Buff. Soc. N. H., I., 90,
